fdf929ff91 Add support for the TFTP windowsize option described in RFC 7440.
The windowsize option permits multiple blocks to be transmitted
before the receiver sends an ACK improving throughput for larger
files.

7dbe228c6a tftp(1): switch default transfer mode to binary
netascii is obsolete and inefficient. It isn't even supported by many

ca2d3691c3 Fix several Coverity warnings in tftp
Some of the changes are in the libexec/tftpd directory, but to functions that
are only used by tftp(1) (they share some code).

* strcpy => strlcpy (1006793, 1006794, 1006796, 1006741)
* Unchecked return value and TOCTTOU (1009314)
* NULL pointer dereference (1018035, 1018036)

d3953c1f47 tftpd: Flush files as soon as they are fully received
On an RRQ, tftpd doesn't exit as soon as it's finished receiving a file.
Instead, it waits five seconds just in case the client didn't receive the
server's last ACK and decides to resend the final DATA packet.
Unfortunately, this created a 5 second delay from when the client thinks
it's done sending the file, and when the file is available for other
processes.

Fix this bug by closing the file as soon as receipt is finished.

e4803b1c14 Fix uninitialized warning, and work around a bug in gcc over clobbering
Summary:
r329077 caused gcc to emit uninitialized use warnings.  Attempting to
fix those warnings yielded the following warnings:

usr.bin/tftp/main.c: In function 'main':
usr.bin/tftp/main.c:181: warning: variable 'el' might be clobbered by
'longjmp' or 'vfork'
usr.bin/tftp/main.c:182: warning: variable 'hist' might be clobbered by
'longjmp' or 'vfork'

This is a known bug in gcc, found at
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=24239

Work around that by simply marking hist and el as static.

8a16b7a18f General further adoption of SPDX licensing ID tags.
Mainly focus on files that use BSD 3-Clause license.

The Software Package Data Exchange (SPDX) group provides a specification
to make it easier for automated tools to detect and summarize well known
opensource licenses. We are gradually adopting the specification, noting
that the tags are considered only advisory and do not, in any way,
superceed or replace the license texts.

Special thanks to Wind River for providing access to "The Duke of
Highlander" tool: an older (2014) run over FreeBSD tree was useful as a
starting point.

b3608ae18f Replace index() and rindex() calls with strchr() and strrchr().
The index() and rindex() functions were marked LEGACY in the 2001
revision of POSIX and were subsequently removed from the 2008 revision.
The strchr() and strrchr() functions are part of the C standard.

This makes the source code a lot more consistent, as most of these C
files also call into other str*() routines. In fact, about a dozen
already perform strchr() calls.

c54da67276 Fix transfer statistics in the "send file" case - The conditional used
to print the stats were using an uninitialised variable. [1]

Fix trasnfer statistics in the "receive file" case - the statistics struct
was being cleared both before and after the initial connect to the remote
server.  As a result, the printed time and calculated bandwidth covers
the time to connect ad well as the time to transfer the file.  This may
not be ideal, but now at least matches the "send file" case.
